Aldrich was a theologian, historian (co-editor of Clarendon's Rebellion), architect (of Peckwater Quad, Christ Church) and Vice Chancellor of Oxford University. This anthem (printed in Boyce) shews him to have been as capable a musician as he was enthusiastic.

Lyrics: Psalm 136 v.1

O give thanks unto the Lord, for he is gracious and his mercy endureth for ever. Hallelujah.
